There is not one answer to address whether marijuana use has increased, decreased, or stayed the same given changes in state legalization of medical and non-medical marijuana in the USA.
Evidence suggests some health benefits for medical marijuana; however, initiation of marijuana use is a risk factor for developing problem cannabis use. Though use rates have remained stable over recent years, about one in three 10th graders report marijuana use, most adolescents do not view the drug as harmful, and over 650,000 youth aged 12 to 17 struggle with cannabis use disorder.
Although the health benefits of medical marijuana are becoming better understood, more research is needed. Intervention and prevention programs must better address effects of marijuana, acknowledging that while there may be some benefits medically, marijuana use can affect functioning during adolescence when the brain is still developing.
鉴于美国医用和非医用大麻的州合法化情况发生了变化，对于大麻使用是增加、减少还是保持不变，并没有一个确定的答案。
有证据表明医用大麻对健康有一些益处；然而，开始使用大麻是发展成问题性大麻使用的一个风险因素。尽管近年来使用率保持稳定，但约三分之一的十年级学生报告使用过大麻，大多数青少年并不认为这种药物有害，并且超过65万12至17岁的青少年在与大麻使用障碍作斗争。
尽管医用大麻对健康的益处正得到更好的理解，但仍需要更多研究。干预和预防项目必须更好地应对大麻的影响，认识到虽然在医学上可能有一些益处，但大麻使用会在大脑仍在发育的青春期影响其功能。
